Basically this is very simple:

You get 2.000.000 per race regardless if you scored any points just having a complete team is enough.

You can earn some extra cash when you guessed the pole time right. The more accurate you are the more money you earn.

You get 50.000 per point you score with your complete team (incomplete teams don't get points)

You get points for all of your team items (driver 1, driver 2, chassis and engine).

Only the first 10 in the qualify and the race get points.

The point distribution is as follows:
